An aspheric lens for glasses is flatter and thinner in design. Standard lenses have a spherical front surface, which means they have the same curvature across the entire lens (i.e. football/tennis ball). With an aspheric lens, the curvature will change gradually from the centre to the edge of the lenses. These lenses are recommended especially for high or strong prescriptions and suitable for myopia (short-sightedness) and hyperopia (long-sightedness). Aspheric lenses are generally more expensive because of its premium lens design and added benefits, making them a great investment.
Made with “high-index lens” materials, they produce a slimmer profile that is also lighter than standard lenses and due to its flatter curvature, aspheric lenses will be closer to your eyes. Glasses wearers will have a more natural look and view, as unwanted magnification and minification will be reduced. This is because standard lenses for myopia will make objects look smaller and the wearer’s eyes will appear small. Whilst, standard lenses for hyperopia will make things look larger and closer than they are in fact. As a result, the wearer’s eyes will appear bigger. Being light in weight, aspheric lenses are also more comfortable and easier to wear, not to mention more cosmetically appealing.
